Mortise-and-Tenon

Definition

A joint in which a tongue-like protrusion (tenon) on the end of one piece is tightly fitted into a rectangular slot (mortise) in the side of the other piece. A joint made by cutting a hole, or mortise, in one piece, and a tenon, or piece to fit the hole, in the other.

Purpose

Mortise-and-tenon joints are used to create strong, durable connections in woodworking and joinery. This traditional jointing technique is known for its stability and load-bearing capacity, making it ideal for furniture making, cabinetry, and timber framing.

Examples of Use

• Furniture making: Assembling tables, chairs, and cabinets using mortise-and-tenon joints for strength and durability.
• Timber framing: Constructing timber-framed buildings with robust mortise-and-tenon connections between beams and posts.
• Door frames: Securing door frames with mortise-and-tenon joints for a stable, long-lasting fit.

Related Terms

• Mortise: The rectangular hole cut into one piece to receive the tenon.
• Tenon: The tongue-like protrusion on the end of a piece of wood that fits into the mortise.
• Joinery: The craft of assembling wooden parts to create structures or furniture.

Notes

• Mortise-and-tenon joints can be reinforced with glue, pins, or wedges for additional strength.
• The fit between the mortise and tenon must be precise to ensure a secure connection.
• This jointing technique is highly valued in traditional woodworking for its aesthetic appeal and mechanical strength.
